Electric Hydraulic Marine Knuckle boom Crane

Electric hydraulic marine knuckle boom cranes have compact structure that can minimize the occupying space on the platform and ship. Furthermore, the operation of knuckle-jib is flexible and changeable. The hook can touch the sea when the wire rope is not spooled off. The cranes can be used for handling the precision instrument and be widely used for the fishing boat, research boat, engineering vessel, naval vessel and special vessel.
Using an articulated jib ("knuckle jib" or "folding jib"), the jib head can be presented close to the load, in order to minimize the pendulum effect. Only limited space is needed for stowing the crane in parked position.
